killall esd trick, pstree weirdness

After playing for a while with 64Studio , and trying some packages to change the look and feel of the desktop environment , suddenly I got an error message while starting Jack Control .

I posted a request for help on the 64studio users mailing list . (read it here)

The process esd was already using the hw:0 soundcard, so I could start qjackctl after first doing killall esd. (with Alacarte Menu Editor, it's easy to change the command in properties for Jack Control to "killall esd & qjackctl")
A second option is to go to the GNOME menu, then Desktop , Preferences , Sound , and disable software sound mixing (ESD) .
The third option is to replace libesd0 with libesd-alsa0, this way esd can keep running while I start qjackctl.

Something I still have to try out one day is what Ralf proposed to do here , I just didn't take the time to figure it out yet.

installed 64studio again

this is an old post

Yesterday I installed an old version of 64Studio again, and upgraded it to the most recent (2) (no cd or dvd needed, it all works with a simple 64studio dummy package after which I "apt-get 64studio-upgrade" (as root).

Now I'm back with the usual configuration stuff to deal with:
the mobo's onboard sound card is recognised first so put on hw:0
but I want my Delta 1010 to be the default card.

my first useful command is:

peter@64studio:~$ cat /proc/asound/cards
0 [I82801DBICH4 ]: ICH4 - Intel 82801DB-ICH4
Intel 82801DB-ICH4 with AD1981B at 0xfebff800, irq 209
1 [M1010 ]: ICE1712 - M Audio Delta 1010
M Audio Delta 1010 at 0xdc00, irq 185
2 [M2x2 ]: USB-Audio - MidiSport 2x2
M-Audio MidiSport 2x2 at usb-0000:00:1d.0-2, full speed

(in ubuntu this would be

peter@64studio:~$ asoundconf list

but if do that command in 64studio, i get

Names of available sound cards:

with no cards listed)

Then I edited the /etc/modprobe.d/alsa-base file and added

alias snd-card-0 snd-M1010
options snd-M1010 index=0
alias snd-card-1 snd-I82801DBICH4
options snd-I82801DBICH4 index=1
alias snd-card-2 snd-M2x2
options snd-M2x2 index=2

to the end of it.
Let's see if it works ... I'll restart, because I don't know the command to reload the alsa-base file
